“Johkasou” in Japan
8,600,000 units of “Johkasou” placed in Japan
Approx.160,000 units of “Johkasou” were
installed in Japan in 2008 for domestic use.
In 1969, we started development of “Johkasou”
That can treat only night soil(flush toilet water)
In 1986, we launched new “Johkasou” that can
treat both night soil and gray water.
Since then, a new high-performance product
development continues.
Now we manufacture approx. 20,000 “Johkasou”
in a year.
